To configure the project-specific Osmorc settings

The drop-down list contains all the framework instances defined for the currently running IntelliJ IDEA at the IDE level. If the framework instance you need is missing, switch to the Framework Definitions tab and define the required instance there.

The drop-down list shows the names of the framework instances followed by the name of the used framework integrator in parentheses. In case you are opening a project created with another installation of IntelliJ IDEA which does not yet have the framework instance used by the project, undefined will be shown where normally the name of the framework integrator appears. If that is the case, switch to the Framework Definitions tab and define the framework instance.

To have the specified framework instance created for the module, select the Create and maintain the module Framework Instance checkbox.
